Since this is a prototype bus stuffing driver you can only run this bin on an actual harmony cart.

Rather than having a full frame buffer it only stores the color and height for each of the 40 columns. There should be plenty of resources left to make an actual game. The quantity of sprites will be severely limited though because the only way to reposition them will be via HMOVE. Joe's demo was used as a reference for some of the fixed point math implementation.

BUS stuffing worked in Stella at one point, but we haven't done much with it since the scheme has basically been abandoned. I'm willing to work with whoever wants to update Stella to get this working again.
